The American Mathematical Association of Two-Year Colleges was founded in 1974. It is the only organization exclusively devoted to providing a national forum for the improvement of mathematics instruction in the first two years of college. AMATYC has approximately 1,800 individual members, including more than 150 institutional members in the United States and Canada. Educators in 47 states and one Canadian province are represented through AMATYC's 44 affiliate organizations.

AMATYC provides professional development opportunities for educators interested in the first two years of collegiate mathematics instruction through an annual conference, webinars, traveling workshops, publications and projects.

AMATYC works extensively with other national organizations. It is a member of the Conference Board of the Mathematical Sciences (CBMS). AMATYC cooperates with the Mathematical Association of America (MAA), the National Council of Teachers of Mathematics (NCTM), the American Statistical Association (ASA), the American Association of Community Colleges (AACC), Mu Alpha Theta (MAT), and other professional organizations.
